fix: .NET 11 exception for dateselected custom event

[jjonescz]

🐛 Bug Report

When using this library on .NET 11, I'm getting an exception in the browser Dev Console:

"The custom event 'dateselected' cannot have the same name as its browserEventName 'dateselected'. Choose a different name for the custom event."

💻 Repro or Code Sample

You can see it on for example https://lab.razor.fyi/, but I assume any FluentUI blazor app on .NET 11 Preview 1 would hit it.

🤔 Expected Behavior

Doesn't crash.

😯 Current Behavior

There is an unhandled exception "The custom event 'dateselected' cannot have the same name as its browserEventName 'dateselected'. Choose a different name for the custom event."

💁 Possible Solution

Change the custom event name to be different from browser event name.

🔦 Context
